Hmm, I'm not sure (a NetCDF expert may want to chime in here), but I think that the variable/columns you are referring to in NetCDF are actually the equivalents of leaves in PyTables (datasets in HDF5). Having said this, I'm afraid that there is no way to attach an HDF5 attribute to columns in Table objects (other than using a convention for attaching attrs to the table in the form: 'column_XXX_myattr', where XXX is the column name). -- Francesc Alted ------------------------------------------------------------------------------ Beautiful is writing same markup.
